In addition to the audible click that can be heard when locking the detachable BMU tow ball, we have added an extra safety feature: the BMU safelock. The key can only be taken out when the tow ball is placed correctly! This way, the signal colour is always leading. All detachable BMU tow balls will be delivered with the new safelock, but it is a running change. This means that all new produced towbars will be delivered with the Safelock feature. BMU towbars delivered with a safelock will of course include an updated instruction manual.
